What is a volume converter?
A volume converter changes a measurement of capacity between units such as millilitres, litres, cups, pints and gallons. Note that US and imperial (UK) units of the same name differ, so check which system you need.
How it works
Each unit has a fixed ratio to the litre. The converter turns your value into litres, then into the unit you choose. US customary defining values are exact: 1 US gallon = 3.785411784 L and 1 US cup = 236.5882365 mL.

How to use
Type a value, pick the unit you have it in and the unit you want it in. The result updates instantly.
All conversions go through liters using exact factors (1 US gallon = 3.785411784 L, 1 US cup = 0.2365882365 L).
Note: the customary units here are US customary. UK/imperial cups, pints and gallons are different sizes — don't mix the two systems in a single recipe.
